  • Dataset Abstract
    These data represent stable isotopic signatures of selected macrofossils from soil cores from Shark Slough sites, including FCE LTER site SRS3. Soils from 1-cm depth increments were analyzed for macrofossil content (mainly seeds) and seeds were processed for d13C and d15N isotopic signatures. These analyses contribute to a paleoecological study to quantify past changes in vegetation and soil accumulation in relation to past climate variation, fire occurrences and water management.

    Sampling Description
    Isotopic analyses of soil macrfossils collected at each sampling site

    Method Step

    Description
    d13C and d15N stable isotopic signatures were obtained from macrofossils of sawgrass (Cladium jamaicense) at specific depth intervals from a short soil core. Seeds were collected from macrofossil analyses (seed ST_SS_Saunders_003) of soil cores. Seeds were inspected under a dissecting microscope and cleaned of rootlets and organic debris. Seeds were rinsed with DI water and oven dried at 80 degrees C. Dry seeds were analyzed for 15N and 13C at the SERC Stable Isotope Laboratory at Florida International University using standard elemental analyzer isotope ratio mass spectrometer (EA-IRMS) procedures. Standards are Peedee Belemnite (PDB) for carbon and air (AIR) for nitrogen.
